The U.S. Environmental Protection Agency, in partnership with UPS, will test a new hydraulic delivery truck on the city streets of Detroit this summer that offers fuel savings, cleaner air, and less noise.

The new system replaces a truck’s transmission with hydraulics and that, combined with a low-emission diesel engine, yields a 60 percent to 70 percent saving on fuel use…The delivery company, United Parcel Service partnered with the EPA; Eaton; International Truck and Engine Corp., UPS’ largest supplier; and the Army in February 2005 to develop a green fleet of low-emissions vehicles.
